Question

find the slope of a line L2 that is parallel to L1 where L1 is -4/3Find the slope but now L1 and L2 are perpendicular

Answer 1

Let:

m1 = Slope of the line L1

m2 = Slope of the line L2

If two lines are parallel we can can conclude:

`\begin{gathered} m1=m2 \\ where: \\ m1=-(4)/(3) \\ so: \\ m2=-(4)/(3) \end{gathered}`

Answer:

-4/3

------------------------

If the lines are perpendicular, we can conclude:

`\begin{gathered} m1\cdot m2=-1 \\ where: \\ m1=-(4)/(3) \\ so: \\ m2=-(1)/(-(4)/(3)) \\ so: \\ m2=(3)/(4) \end{gathered}`

Answer:

3/4
